Coolant System

When the coolant pump is turned ON, the fluid is delivered through the nozzle attached to the carriage. The flow is controlled by the valve lever at the base of the nozzle (see Figure 87).

Always use high quality coolant and follow the manufacturer's instructions for diluting. The quick reference table shown in Figure 88 can help you select the appropriate fluid.

Refer to Coolant System Service on Page 71 for detailed instructions on how to add or change fluid. Check the coolant regularly and promptly change it when it becomes overly dirty or rancid, or as recommended by the ﬂuid manufacturer.

BIOLOGICAL & POISON

HAZARD!

Use the correct personal protection equipment when handling coolant. Follow federal, state, and fluid manufacturer requirements for proper disposal.

Running the pump without adequate fluid in the coolant tank may permanently damage it, which will not be covered under warranty.

To use the coolant system on your lathe:

1.Make sure the coolant tank is properly serviced and filled with the appropriate fluid, and that you are wearing the necessary personal protection equipment.

2.Position the coolant nozzle for your operation.

3.Use the coolant pump switch on the control panel to turn the pump ON.

4.Adjust the flow of coolant by using the valve lever near the base of the nozzle hose.

Important: Promptly clean any splashed fluid from the floor to avoid a slipping hazard.

General Note: Coolants are used for heavy-duty lathe operations and production turning. Oil-water emulsions and synthetic cutting fluids are the most common for typical lathe operations. Sulferized oils often are used for threading. For small projects, spot lubrications can be done with an oil can or brush, or omitted completely.
